      Under the dash sometimes hard to find, its 14 pin connector that looks like the end of the diagnostic tool, it can also be under the hood

    AC Compressor Needs Replacing. Would appreciate DETAILED instructions on proper replacement. Thank you.
    2007 Toyota Highlander with 2.4L engine. AC Compressor shot. Mechanic wants $900 to do complete job. Sounds about right, but I dont have the scratch. I am fairly mechanical. I know there are "tricks to the trade" with replacing AC compressors. Would anyone be ...

      Each component in the A/C system is dependent on other parts of the system to operate properly. It is important that each component be of the highest quality, and installed in a clean, well lubricated system in order to insure proper operation.
      Don't just replace the malfunctioning component. System repair typically involves the flushing and replacement of additional parts and fresh lubricant to put it back in proper operating condition. For example if you open the system to replace the compressor, the system should be flushed and all o-rings and seals replaced, as well as other major components, such as the expansion valve, receiver/drier, and/or orifice tube.
      The a/c compressor kit cost is around $200.00 - 250.00 - parts alone. Sources; www.aptopartswarehouse, www.partsgeek.com, www.rockauto.com - to list only a few.

      Try these websites for the details and instruction steps; www.autozone.com, www.autoacsystems.com, or the the local library in your area for the repair manual.

    Engine knock under light load at 50+ mph - economy at 50mpg.
    72,000 miles. With engine warmed up - 10 miles or so, cruising at 50+ with cruise control on and on the level - I can hear a knocking from the engine. Economy shows 50mpg or so. When you go up a grade the knock stops (economy down to 20 or 30mpg) - when economy goes ...

      As a first step and it doesn't need the check engine light to be ON, have the vehicle scans it and retrieve it any diagnostic codes stored in the PCM.
      Also, it could be the knock sensor.

      Sensor mounted near the cylinder bores in the cylinder block. Used to detect engine knocking and to retard the ignition correspondingly in order to prevent engine damage. Prevent expensive engine damage that can occur from a malfunctioning sensor.

    Engine overheated and died on the road. Now will not start.
    Engine coolant at proper level at the time of overheating. Timing belt cover melted at contact points to engine. Does this mean head is warped? Do I need new head or is there probability of machining it back to shape? Engine has 120000 on it.

    What happened to my engine?
    I was driving this weekend and all of a sudden, the engine started making loud banging noises when I was accelerating. I noticed the oil gauge had dropped extremely low. I pulled over and put two quarts of oil into the car. Let it run for a bit, no noises. I drove ...

      The fix really depends on the damage done. It seems like you either blew a head gasked or lost a drastic amount of oil in a short period. Is there any way you could describe the banging noise? If possible post a video with a link I would be interested to know. I hope it's not a spun bearing. In that case you'd likely need a new engine. I know toyota builds great engines so hopefully whatever happened can be repaired without having to put a new engine in

    There is a shaking in my car, but only when pressing the gas pedal at approx 50+ mph (3,500+ rpm). Any ideas?
    The shaking stops when the throttle is released or clutch is applied. It was recently repaired after a small wreck. I took it back to the body shop where repairs were done, but they could not find what was causing the shaking. There is also a popping noise in the ...

      Sounds like bad tires or tire, you need to get them balanced and see which one it is

      I'm sorry...and I should've mentioned this in my initial description. I had all 4 tires replaced and an alignment done this past weekend. It doesn't shake in the steering, just underneath my body when accelerating at 45+ mph.

    Coolant appears to be leaking from below the throttle body/IAC area.
    2002 Toyota Highlander Limited has about 167,000 miles. It only appears to leak when started and while running. Once coolant is completely drained the engine overheats. This problem just began two days ago when my engine began to overheat while driving. I opened ...

      Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

    The car is shaking in idle, dash lights are on (check engine, vsc, slip indicator), and A/C is only partially working
    My car is just over 100k miles and my last oil change was 1k miles ago. About once or twice a month three dash lights (check engine, vsc, and slip indicator) will randomly come on when I start the car. The next time I start the car, however, they go off. Two days ...
